Review: Great Price And Good Batteries - I think this was a pack of 2 so I am all set now. I never even knew these were available and I was ready to throw the phone away. Now it works well and you can talk a long time. Review: we had some issues finding a cordless phone that would actually work longer then a few months to a year without some sort of iss - I have had a set of 4 Uniden cordless phones for YEARS. At the time, we had some issues finding a cordless phone that would actually work longer then a few months to a year without some sort of issue (they don't make things like they use to I guess). The Unidens we purchased were actually inexpensive... Which was a HUGE plus... And they worked great!! They stood up through 3 toddlers and hard wood floors. It broke my heart when these started to give us an issue. It was like overnight all 4 phones would die after 10 min of talking on them (but remember... This was after YEARS of use). I really didn't want to give them up. I wasn't positive it was the batteries that were going... But I figured I'd try changing them out before I looked into new phones. I bought a 2 sets of these and my phones work perfectly again!! They hold the charge (like they are brand new), they were SO easy to install and the price was right too!!! I also want to mention that I had to contact the seller.. Who was AWESOME and so easy to deal with... And SO nice!!! I wanted to give them kudos for that 😃 ## Features - Genuine OEM Uniden BT-1021 BBTG0798001 Cordless Handset Rechargeable Battery (2-Pack) - Produced by Corun (as pictured) - Nickel Metal Hydride, 2.4V DC; 300-mAh - Compatible with Phone Models: D1361, D1361BK, D1364, D1364BK, D1384, D1384BK, D1384-2, D1384-2BK, D1384-4, D1384-4BK, D1483BK, D1483W, D1660, D1660-2, D1660-2T, D1660-3, D1660-4, D1680, D1680-2, D1680-3, D1680-3T, D1680-4, D1680-8, D1685, D1685-2, D1685-3, D1685-4, D1685-5, D1688, D1688-2, D1688-2T, D1688-3, D1688-4, D1688-5, D1760, D1760-2, D1760-2W, D1760-3, D1780, 1780-2, D1780-2BT, D1780-2W, D1780-3, D1780-3BT, D1780-4, D1785, D1785-2T, D1785-2T, D1785-3T, D1788, D1788-2, D1788-3, D2997, D2998, D3097, D3097S, D3098, D3098S, D3580-2, D3580-3, D3588, D3588-2, D3588-3, DECT1363BK, DECT2060, DECT2060-2, DECT2080, DECT2080-2, DECT2080-2W, DECT2080-3, DECT2080-4, DECT2080-5, DECT2085, DECT2085-2, DECT2085-2W, DECT2085-3, DECT2085-4, DECT2085-4WX, DECT2085-5, DECT2088, DECT2088-2, DECT2180, DECT2180-2, DECT2180-3, DECT2180-4, DECT2185, DECT2185-2, DECT2185-3, DECT2188, DECT2188-2, DECT2188-3, DECT2188-4, DECT2188-5, DECT2662, DECT2662-2, DECT2882, DECT2882-2, DECT2882-3, DECT2888, DECT2888-3, DWX207, WXI2077, DCX160, DCX170, DCX170BT, DCX170T, DCX170W, DCX200, DCX210, DCX291, DCX309, DCX350. - Compatible Replacement for Batteries: BT-1016, BT-1008, BT-1025, CPH-515B. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00Y57KOC8 | | Amperage | 2.4 Amps | | Antenna Location | Phone | | Battery Capacity | 300 Milliamp Hours | | Battery Cell Composition | NiMH | | Battery Cell Type | NiMH | | Best Sellers Rank | #81 in Cordless Telephone Batteries | | Brand | Uniden | | Customer Reviews | 4.6 out of 5 stars 1,890 Reviews | | Item Weight | 0.02 Pounds | | Manufacturer | Kastar | | Model Name | bbtg0798001 | | Model Number | BT-1021 | | Number of Batteries | 2 AAA batteries required. | | Recommended Uses For Product | Phone | | Reusability | Rechargeable | | UPC | 682055280035 | | Unit Count | 2 Count | | Voltage | 2.4 Volts | ## Product Details - **Battery Capacity:** 300 Milliamp Hours - **Battery Cell Composition:** NiMH - **Brand:** Uniden - **Number of Batteries:** 2 AAA batteries required. - **Recommended Uses For Product:** Phone ## Images ![New Genuine OEM Uniden BT-1021 BBTG0798001 Cordless Handset Rechargeable Battery (2-Pack) - Image 1](https://m.media-amazon.com/images/I/61CRL5l2-IL.jpg) ![New Genuine OEM Uniden BT-1021 BBTG0798001 Cordless Handset Rechargeable Battery (2-Pack) - Image 2](https://m.media-amazon.com/images/I/61qYDDUh0-L.jpg) ## Questions & Answers **Q: It says to charges he new battery for 20 hours before placing in phone. How or with what do we charge them other than in the phone** A: Just put the battery into the phone and place the phone in the phone charger for 20 hours. That will charge the battery. **Q: Are these batteries fully charged or do I need to charge them before use?** A: As with all batteries. You should fully charge them before use. Especially Nickel cadmium's. **Q: it says must be disposed by 2015, and we almost done with 2017! are these batteries have the same expiration date as is shows in the photo?** A: The text is meant to be read as "must be disposed of properly". The year that appears on the battery is actually the year of production, not the expiration date. **Q: is there a oem battery with better amh than this 300 amh batt, for the Uniden 6.0 Dect 2180 (-2)? How old are these?** A: I do not know if there are better amh batteries out there and there's no date on the battery or the package. That being said, I've had them for over a month now and no problems so far. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Price And Good Batteries *by D***N on January 4, 2026* I think this was a pack of 2 so I am all set now.
